描述
disp_ellipsedisp_ellipseDispEllipseDispEllipseDispEllipsedisp_ellipse displays one or several ellipses in the
output window. An ellipse is described by the center (CenterRowCenterRowCenterRowCenterRowcenterRowcenter_row,
CenterColCenterColCenterColCenterColcenterColcenter_col), the orientation PhiPhiPhiPhiphiphi (in radians) and the
radii of the major and the minor axis (Radius1Radius1Radius1Radius1radius1radius_1 and
Radius2Radius2Radius2Radius2radius2radius_2).
The operators used to control the display of regions
(e.g., set_drawset_drawSetDrawSetDrawSetDrawset_draw, set_grayset_graySetGraySetGraySetGrayset_gray, set_drawset_drawSetDrawSetDrawSetDrawset_draw)
can also be used with ellipses. Several ellipses can be displayed
with one call by using tuple parameters. For the use of colors with
several ellipses, see set_colorset_colorSetColorSetColorSetColorset_color。
注意
The center of the ellipse must be within the window.
